  • ROSOR's Specialized RPAS Technology for Geophysical Surveys; Comparison and Downstream Impact

    We go through the features of ROSOR's specialized technology by comparing it to both traditional aircraft and standard RPAS with actual results comparison and highlighting ROSOR's downstream impact. In previous posts, we discussed the challenges and drawbacks of present-day mineral exploration's airborne geophysical surveys by traditional aircraft, and we introduced, what we consider, the future of mineral exploration by highlighting the main features of ROSOR specialized RPAS technology. Today we will present a comparison between ROSOR technology and all other available airborne geophysical surveys options based on actual performance results ROSOR performance in the field Vs. Traditional Aircraft ROSOR specialized technology Vs. standard drone (RPAS) Total comparison; ROSOR technology vs. Traditional aircraft & Standard RPAS. ROSOR specialized RPAS Downstream Impact ROSOR performance in the field Vs. Traditional Aircraft For our latest case study, we compare a small, approximately 200-kilometer total magnetic intensity survey flown by our RPAS and another survey by a traditional airplane. Our RPAS paths in this operation towed a Geometrics MagArrow, which utilizes a thousand-hertz sampling rate, and the aircraft was flown at approximately a hundred kilometers per hour. Here's a sample of the resulting magnetic map produced by the traditional airplane, a NAVAJO PA-31. And right away here you can see in our same survey flown by our specialized system with that single mag, the flight produced a higher total magnetic intensity resolution. The approximate 200 kilometers were flown at approximately two hours of flight time. It had a 15-meter line spacing, again, a thousand-hertz sampling frequency, low first and fourth difference meeting industry standards, and low noise. It was fully electric and emission-free. And finally, of course, remotely piloted. Now having the towed sensor provided a much more favorable signal-to-noise ratio outputting high-quality raw data without the need for heavy noise compensation techniques. A thousand-hertz frequency provided much more coverage than the typical 10 hertz in a traditional mag, and also gave post-processing much more flexibility. And finally, the speed at which the survey was completed shows our crew's ability to comfortably complete 500 to 800 inline kilometers on any given day. ROSOR specialized technology Vs. standard drone (RPAS) Given such coverage capabilities, our specialized RPAs are not to be confused with typical small multirotor RPAs that are commonly seen in geophysical space. For these small surveys that cover less than a few hundred kilometers, or typically less than a thousand, at most, our survey crews are able to cover much larger areas with specialized RPAs that can fly over a hundred kilometers per flight and quickly get back up in the air with swappable battery packs. That with the added bonus of faster speed makes for much greater coverage. This provides our crews with the ability to take on mineral exploration surveys, typically, again, between 1000 to 10,000 inline kilometers. In comparing ROSOR RPAS with other fixed-wing RPAS in aero-magnetic space, these models tend to produce highly filtered data results due to the low signal-to-noise ratio during that acquisition. These electric aircraft fixed wings typically seen on the market produce their own electromagnetic field, which introduces noise into the magnetic readings measured with flux state systems that need to be compensated for during post-processing, our specialized systems with external sensors to our aircraft allow for separation between sensors and noise producing motors. This separation escapes the noise and produces raw data output that remains less altered to give clients true readings into their survey areas. Total comparison; ROSOR technology vs. Traditional aircraft & Standard RPAS. Now broadening our scope and comparing all airborne data acquisition options, we focus on five main metrics, cost per inline kilometer, coverage, data resolution, navigation, and payload. In reviewing helicopters, they excel in payload capacity and range with fairly good data resolution, along with quite good navigation, but it's very expensive, in fact, one of the most expensive options. Airplanes, it's much less expensive per inline kilometer, but that data resolution rat suffers. In typical multirotor RPAs, the resolution and navigation abilities are the highest, but the high cost makes it prohibitively expensive on a scale. The ROSOR RPAS excels in each category by lowering the cost for inline kilometer maxing cover, maximizing coverage, navigation, and data resolution, while maintaining payload capacity suitable for necessary onboard sensors. Therefore, the ROSOR RPAS offers not only the high-resolution benefits of drone systems (RPAS), but also the scalability of traditional aircraft. ROSOR specialized RPAS Downstream Impact Now deploying specialized systems also introduces great benefits downstream promoting pilot safety, a cleaner environment, and fewer additional costs down the road. Safety We have, of course, remote navigation operating conditions that are much safer. As RPAs remove the pilot from the aircraft, thereby removing the most dangerous type of flying low altitude flight for the environment. Environment The specialized system has a net zero emission during acquisition, creating a greener alternative for mining companies and reducing their scope-three emissions. Cost Lastly, but probably most importantly, these high-resolution scans are capable of reducing costs by eliminating unnecessary secondary ground-level scans due to the optimized performance during flight. In addition, the need for secondary surveys, post-processing, and analysis from expensive geophysicists is reduced, which in turn decreases the amount of investigation time overall. So, whether you're mining companies looking for a better alternative in conducting mineral exploration, airborne surveyors and geoscience firms interested in onboarding cost efficient platforms to reduce operational costs, sensor manufacturers searching for the right platform to integrate your technology or even outside the mining industry.

  • Future of Mineral Exploration | ROSOR's Specialized Technology

    Know about the specialized technology of ROSOR's drones for mineral exploration and preforming higher quality geophysical data acquisition In a previous post we discussed the environmental impact and economic drawbacks of traditional aircraft geophysical surveys, and we ended with the question How do we solve issues, such as Environmental damage, High cost and time wasted, and requirement for Compound Data Analysis. Today we will present the future of mineral exploration, that is available now, with ROSOR's specialized technology. With rapidly deployable operational crews that utilize long range Remotely Piloted Aircraft Systems (RPAS) capable of flying low to the lower to the ground, and closer to their point of interest, these specialized systems are able to yield high resolution data, even comparable to ground level surveys. Currently, in our case, we focus primarily on magnetic data with a single onboard magnetometer with our specialized remotely piloted aircraft. In this post we will discuss the main advantages of ROSOR's specialized UAV-based technology for mineral exploration through these main points; Increased Resolution Increased Coverage Minimized Cost Fully Certified RPAS service Increased Resolution With ROSOR's specialized remotely piloted aircraft systems that are lightweight and much more maneuverable, these systems are capable of flying as low as possible to the ground with a minimal buffer flying lower to the target of interest gains the lost potential experienced with traditional aircraft. Then by acquiring high resolution data at nearly ground level quality, this can remove the need for further ground level scans altogether, along with the secondary accompanying post-processing and analysis from geophysicists Increased Coverage With ROSOR long-range systems, a large survey area can be completed efficiently with project sizes typically much larger than your AVI RPAS. Our systems can serve us between 1000 to 10,000 inline kilometers in any single project, with fully qualified operational RPAS. Crews ready to roll out at a moment's notice in combination with vertical takeoff and landing systems that don't require full runways for takeoff and landing. Deploying specialized RPAsS is very fast and much more operationally flexible than traditional aircraft. Minimized Cost Even more importantly, with only one scan required for the entire investigation, that acquisition is of course much faster. In addition, there's the benefit of less post-processing and analysis, making the overall investigation all that much faster and more cost efficient. Fully Certified RPAS service specialized technology also requires specialized pilots and crew members to operate them. Our pilots and field operatives all come fully certified with, at minimum an advanced RPAs operations certificate and follow our standardized operational procedures designed to meet Transport Canada standards. Our pass with long range capabilities and with our operational safety management system in place make beyond visual line of sight operations a possibility. We have a structured method for acquiring special flight operation certificates or SFOCs wherever necessary for larger surveys where they're suitable. To know more about Transport Canada SFOC's and ROSOR's successful Special Flight Operations certification Read this post We have discussed the main advantages of ROSOR specialized technology, but how does its downstream impact differ from other aerial geophysics survey options? How does its product (Geophysical surveys data) compare to other RPAS / Drone-based solutions? and even to the traditional aircraft geophysical surveys? That's what we will discuss in our upcoming posts, so stay tuned and watch for it.

  • Environmental Impact and Economic Drawbacks of traditional aircraft geophysical surveys

    Present Day mineral exploration faces many challenges for an already high-risk business, that is known for low success rates. But there are other challenges than economic ones, if you follow the news these days you will see global attention to the climate summit COP27, group of world leaders, industrial key personnel, and environment activists all gather to push for a decrease in the global emissions We will discuss the present and future of mineral exploration, especially the developments in airborne geophysical surveys. We'll start with an overview of present-day exploration, looking into current gaps in the discovery phase of mining projects and the kind of impact it has downstream. From there, we'll get into the future of exploration, showcasing emerging technology in specialized data acquisition, and providing a deeper comparison to traditional methods. We will start with this post and the posts to follow. Our main points today Exploration to this day has experienced tremendous growth, largely due to the capabilities of traditional aircraft in conducting airborne surveys. Historical perspective on airborne geophysical surveys Present-day traditional aircraft geophysical survey Missed Opportunities Modern airborne geophysical survey options Environmental Impact and Economic Drawbacks of traditional aircraft geophysical surveys What's next? Historical perspective on airborne geophysical surveys The roots of successful airborne electromagnetic system development date back to the early 1950's when the International Nickel Company produced the world's first practical airborne EM system (Cartier and others, 1952). This apparatus, which was originally installed in a wooden aircraft to ease development problems, clearly proved the potential of the new exploration technique. Other developments of the 1950s included the Finnish two-frequency quadrature system (Puranen and others, 1960) that used a towed bird and provided compensation for the metal in the aircraft. It was operated in Canada by the Photographic Survey Corporation, a subsidiary of the Hunting Group. This system was quite effective but suffered from noise associated with conductive overburden.[1] Present-day traditional aircraft geophysical survey After these many years, and as the number of airborne surveys increases, so do the complications it has during and post-acquisition. In the initial phase of discovery, emphasized large middle exploration initiatives have utilized traditional aircraft platforms such as helicopters and airplanes to conduct the first round of airborne surveillance. These surveys cover large areas of interest that require anywhere from (1,000 to 10,000s) of inline kilometers. The surveys include onboarding sensors such as magnetic, electromagnetic, radiometric, and many others, however, when integrated into traditional aircraft, the performance of its readings decline due to the aircraft's requirement to fly at higher altitudes. Missed opportunities Now, if there are fewer, less obvious deposits within the specific areas of land, those deposits can even go completely unnoticed with low-resolution traditional aircraft scans, which are less likely to be further investigated on the ground. This presents a serious problem for those involved as this can present a huge opportunity cost. Modern Airborne Geophysical survey options let's take a deeper dive into traditional aircraft and compare its features to the prevailing alternative of remotely piloted aircraft systems or RPAs for short. At this point in time, traditional airplanes and helicopters have been the dominating platform for data acquisition, and with good reason. There are certain specifications that just cannot be beaten by alternatives, including the coverage and payload capacity for sensors. For most applications in mineral exploration, it makes sense to deploy traditional aircraft more often than RPAs Currently, however, there are drawbacks to this platform, which cannot be overlooked, like lower resolution, poor navigation, and much, much higher overall cost. But what happens downstream should always also be closely looked at pilot safety. The environment and further costs in secondary investigations are required with traditional aircraft being that there are no alternatives that can address these concerns in an effective manner, we're situated with the following, Safety hazards, It's challenging to fly at low heights and at low speeds, especially when situated in rough terrain. We should avoid putting pilots in these situations whenever possible, and there should be a better alternative to promote safer working conditions. Environmental damage. As most of the world leaders gather these days for the climate summit COP27 to work on decreasing CO2 emissions, typical small airplanes such as the King Air Navajo Sessna 2 0 8, or small helicopters such as the Bell 2 0 6, MD 500 D and a S three 50 used in mineral exploration within this larger survey category produce on average approximately 1500 to 3000 metric tons of CO2 per year. On fuel alone, there's also the negative impact on manufacturing and the disposal of these aircrafts. This all contributes to the vast amount of Scope three emissions, which is of course the largest group that produces GHG emissions, not just in mining, but in pretty much all industries. High cost and time wasted in post-processing and analysis of low-resolution traditional aircraft survey data. Geophysicists who analyze that data are in short supply and very much in demand. A widespread problem is seen across the industry, especially right now, which makes their service come at a great cost. Compound Data Analysis Having to analyze the data, not only from in the air but also from a secondary data set on the ground, further compounds the problem. This makes for a very expensive and time-consuming investigation. The question is, how do we solve these issues? In our upcoming posts, we'll be presenting a better, faster, and safer way of acquiring airborne geophysical data.
